Description

Technical Field

[0028] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of the embodiments. Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this application. In addition, the technical solutions of various embodiments can be combined with each other, but this must be based on the ability of those of ordinary skill in the art to implement them.

[0029] Reference Figure 4-9 As shown, an adjustable synchronization component includes a timing belt 1 and two timing pulleys 2. The timing pulleys 2 are mounted at both ends of the oval-shaped timing belt 1. An adjustment mechanism 3 is mounted on the timing belt 1 and close to one of the timing pulleys 2. The adjustment mechanism 3 includes a guide 31 and an adjustment member 32. The adjustment member 32 is used to control the tension of the timing belt 1, and the guide 31 is used to limit the movement direction of the adjustment member 32.

[0030] Specifically, such as Figure 4 As shown, the synchronous belt 1 has a notch 4 for dividing the synchronous belt 1. Based on the notch 4, the left and right sides of the notch 4 are the first synchronous belt segment 101 and the second synchronous belt segment 102, respectively. The adjustment mechanism 3 is installed at the notch 4 of the synchronous belt 1. More specifically, the adjustment mechanism 3 can adjust the spacing of the notch 4. Under normal conditions, when the spacing of the notch 4 is a, the synchronous belt 1 is conventionally wound on the synchronous pulley 2. When the spacing of the notch 4 is less than a, the synchronous belt 1 is in a taut state.

[0031] Specifically, a first clamping block 5 and a second clamping block 6 are provided on the first synchronous belt 101 and the second synchronous belt 102 near the edge of the notch 4. The adjusting member 32 and the guide member 31 are installed on the first clamping block 5 and the second clamping block 6. The adjusting member 32 controls the first clamping block 5 and the second clamping block 6 to move closer or further apart. During the movement of the first clamping block 5 and the second clamping block 6, the guide member 31 is used to ensure the stability of the movement direction of the first clamping block 5 and the second clamping block 6 and prevent deviation.

[0032] In order to ensure that the first clamping block 5 and the second clamping block 6 are connected to the first synchronous belt 101 and the second synchronous belt 102 respectively, a first clamping cavity 51 and a second clamping cavity 61 are provided on the first clamping block 5 and the second clamping block 6, which are at the same horizontal plane as the first synchronous belt 101 and the second synchronous belt 102. The movement of the first clamping block 5 and the second clamping block 6 drives the movement of the first synchronous belt 101 and the second synchronous belt 102.

[0033] To stably confine the first segment of synchronous belt 101 and the second segment of synchronous belt 102 within the first clamping cavity 51 and the second clamping cavity 61, preventing them from being pulled, a fastening plate 7 is provided to cooperate with the first segment of synchronous belt 101 and the second segment of synchronous belt 102. A first toothed surface 103 is provided on the lower surface of the synchronous belt 1, and a second toothed surface 71 that meshes with the first toothed surface 103 is provided on the upper surface of the fastening plate 7. When the second toothed surface 71 on the fastening plate 7 meshes with the first toothed surface 103 on the synchronous belt 1, the synchronous belt 1 and the fastening plate 7 in this state are installed into the first clamping cavity 51 and the second clamping cavity 61, thereby achieving the purpose of confining the first segment of synchronous belt 101 and the second segment of synchronous belt 102 on the first clamping block 5 and the second clamping block 6.

[0034] Specifically, the fastening plate 7 is composed of a first straight plate 72 and a second straight plate 73 that are perpendicular to each other. The first toothed surface 103 is disposed on the top surface of the first straight plate 72. The length of the second straight plate 73 is much smaller than that of the first straight plate 72, and the whole is L-shaped. The first straight plate 72 is parallel to the first synchronous belt 101 and the second synchronous belt 102. The two fastening plates 7 are symmetrical on the first clamping block 5 and the second clamping block 6. The inner sidewall of the second straight plate 73 on each fastening plate 7 is attached to the opposite side between the first clamping block 5 and the second clamping block 6.

[0035] It should be noted that, in order to save on profile costs and installation space, the adjusting member 32 and the guiding member 31 are placed horizontally on the first clamping block 5 and the second clamping block 6. Therefore, the first adjusting hole 52 and the second adjusting hole 62 for installing the adjusting member 32, and the first guiding hole 53 and the second guiding hole 63 for installing the guiding member 31 are respectively provided on the first clamping block 5 and the second clamping block 6. The first adjusting hole 52 and the second adjusting hole 62, and the first guiding hole 53 and the second guiding hole 63 are all coaxial.

[0036] Specifically, such as Figure 4 , 5As shown, the left side of the notch 4 is the first segment of the synchronous belt 101, and the right side is the second segment of the synchronous belt 102. The first clamping block 5 and the second clamping block 6 are also respectively disposed on the left and right sides of the notch 4. The adjusting member 32 and the guide member 31 are screwed into the first clamping block 5 from the second clamping block 6. The adjusting member 32 includes an adjusting rod body 321 and an adjusting rod head 322. The guide member 31 includes a guide rod body 311 and a guide rod head 312. After installation, the adjusting rod head 322 and the guide rod head 312 are respectively attached to the right side of the second clamping block 6. The adjusting rod body 321 passes through the second adjusting hole 62 and partially enters the first adjusting hole 52. The guide rod body 311 passes through the second guide hole 63 and partially enters the first guide hole 53.

[0037] It needs further explanation that both the adjusting rod body 321 and the guide rod body 311 are threaded. The adjusting rod body 321 has its tail end near the adjusting rod head 322 and its head end away from the head. The guide rod body 311 has its tail end near the guide rod head 312 and its head end away from the head. The head end of the adjusting rod body 321 is threadedly engaged with one of the clamping blocks, and its tail end is threadedly engaged with the optical axis of the other clamping block. The head end of the guide rod body 311 is threadedly engaged with the optical axis of one of the clamping blocks, and its tail end is threadedly engaged with the other clamping block. Specifically, the first... The second guide hole 63 on the second clamping block 6 is a threaded hole, and the first guide hole 53 on the first clamping block 5 is a spherical shaft hole. The diameter of the spherical shaft hole is slightly larger than the diameter of the guide rod body 311. The second adjustment hole 62 on the second clamping block 6 is a spherical shaft hole, and the first adjustment hole 52 on the first clamping block 5 is a threaded hole. By rotating the adjustment rod head 322, the first clamping block 5 is moved closer to the second clamping block 6, and the first clamping block 5 is prevented from rotating by the restriction between the first guide hole 53 and the guide rod body 311.

[0038] like Figure 2-3 The diagram shows a synchronous beam 8 on which the synchronous assembly is installed. The beam 8 consists of a main beam 81 and a secondary beam 82. The synchronous belt 1 and the synchronous pulley 2 are installed inside the main beam 81. At the same time, a traction member 821 is installed inside the secondary beam 82. The traction member 821 is installed on the synchronous belt 1. When the synchronous pulley 2 rotates, the traction member 821 moves from one side of the synchronous pulley 2 to the other side of the synchronous pulley 2.

[0039] Specifically, the main beam 81 is composed of a rectangular frame and a slotted edge. The upper part of the synchronous belt 1 is placed outside the rectangular frame, and the lower part is placed inside the rectangular frame. Fixing plates 811 are installed on both sides of the main beam 81 and fixed to the rectangular frame with screws. The two synchronous pulleys 2 are installed on the two fixing plates 811 and can rotate. The secondary beam 82 is composed of a sliding groove 822 and a snap-fit ​​edge that cooperates with the slotted edge. The snap-fit ​​edge is fastened to the slotted edge. The sliding groove 822 is located on one side of the synchronous belt 1. The traction member 821 includes a pulley 8211 installed in the sliding groove 822, and a clamping plate is provided on the pulley 8211. It also includes a connecting plate 8212. The connecting plate 8212 connects the first pulley 8211 to one of the clamping blocks, specifically to the second clamping block 6. The connecting plate 8212 is fixed to the clamping plate with screws, and the connecting plate 8212 is fixed to the second clamping block 6 with screws.

[0040] like Figure 1 The image shows a sunshade with the crossbeams 8 installed. The sunshade consists of two opposing crossbeams 8 and a longitudinal beam 9 forming a ring beam. Support columns are set at the four corners of the ring beam to form a frame. A traction rod 10 is set between the opposing pulleys 8211 on the two sets of crossbeams 8. Adjacent traction rods 10 are connected by a canopy 11.

[0041] The working process of this utility model is as follows: The synchronous pulley 2 is fixed on the fixing plates 811 on both sides of the main beam 81. The lower part of the synchronous belt 1 passes through the rectangular frame of the main beam 81. First, the first segment of the synchronous belt 101 and the second segment of the synchronous belt 102 are passed through the first clamping cavity 51 and the second clamping cavity 61 on the first clamping block 5 and the second clamping block 6. The second tooth surface 71 of the two fastening plates 7 are respectively fastened to the first tooth surface 103 of the first segment of the synchronous belt 101 and the second segment of the synchronous belt 102 that have passed through the first clamping cavity 51 and the second clamping cavity 61. Two straight plates 73 approach the notch 4, causing the overlapping portions of the first synchronous belt 101 and the fastening plate 7, and the overlapping portions of the second synchronous belt 102 and the fastening plate 7 to move in the directions of the first clamping block 5 and the second clamping block 6, respectively. The overlapping portions are placed in the first clamping cavity 51 and the second clamping cavity 61, respectively, and are restricted from disengaging from the first clamping cavity 51 and the second clamping cavity 61 by the action of the second straight plate 73. The adjusting member 32 and the guiding member 31 are inserted into the first clamping block 5 and the second clamping block 6, and the adjusting rod head 322 is turned to tighten the synchronous belt 1.
